My 3 year old has asd and I have been advised to get Melatonin for him as he doesnt sleep - I have 2 other children and am knackered. I asked my Doctor to prescribe some but she said no I had to get it from where he was diagnosed. They told me to go back to my GP. My GP has no experience of asd so isnt going to prescribe it. Is there any other place I can get it?
